What type of quests do you prefer?

I like quest chains that have a story.
Kill quests can be ok, if it's something beyond: Oh some undead raided my barn, and stole my chocobo saddle, so now i can't ride; can you go kill 15 undead, and get my chocobo saddle back? I mean...really? It can be ok to do such lame errands for people at low lv, but not over lv 10

Well the example in your pics....are annoying it's more for exploraholics, that don't mind spending a day or weekend, running around the whole world looking for stuff; forcing everyone else to visit wiki. But on the other hand, that's not much different than asking some other NPC, or referring to a book in some in-game library. You're just using another form of communication, to find out your destination; Someone found a fount, and decided to write it down somewhere, in case someone else would find the information useful.

Agree, the problem with loads of trash mob kill quests is usually often the action is already over and you have to report back to an npc for completion. I think SWTOR for example while using kill quests at least mixed it up in their daily "heroic" kill quests some of which did take 20min if done at the recommended level, and would require a party.
